Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.
1.Appearance: white to yellowish powder
2.Viscosity Specification as below
Note: Any other special requirement for the product can be satisfied through the negotiation.
Pharmaceutical aid: HPMC is used as adhesive, solutizer in tablet, film-forming reagents in pharmaceutical coating,delayed-release and controlled-release tablets or capsules, thickener and water-binding agent in liquid formulation, component in eye drop.
The high viscosity specification is widely used in the sustained and controlled release system of hydrophilic gel matrix. The low-viscosity grade is used as the main shell material in tablet coating and non-gelatin capsule formulations, and is also a commonly used binder in wet granulation.

【Transportation and Storage】
The product should be kept in the original bag and stored in the dry and clean place far away from the source of heat and not put together with other chemicals .
The direct addition of the product to water causes the formation of lumps . Lumping results from incomplete wetting of the individual powder particles . Only the powder in contact with water dissolves and the formed gelatinous membrane prevents the remaining powder from dissolving , causing a delay in the dissolution time . The following three methods are recommended for dissolution without forming lumps . The most convenient method should be chosen according to the purpose of your application .
